TO ALL WHOM IT MAY C ONCERN. 'i

Be it known that we, RIcHARD B. Looicnfoi New Orleans, and WILLIAM B. ULRICH', of lConcordia Parish, State of Louisiana, have invented an Improved Gas-Burner; and we do hereby declare the following to bc a full, clear, and exact description thereof, reference being Ahad to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation of an improved burner complete and ready for use.

Figure 2 is an enlarged diametrical section through the improved burner, showing the cock turned so as to cut off the supply of gas to the primary burners.

Figure 3 is a diametrical section with the globularchamber and primary burner removed, showing the cock turnedso as to allow a full iiow of gas to the primary burner.

" Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is 'to construct a gasburner which is adapted for burning all kinds of illuminating gas in such manner that a light can beobtained at any moment by simply turning the cock,` which admits the gas to the burner,'thus producing what we shall denominate a self-lighting burner, and avoiding all the inconveniences attending the use of tapers for lighting gas under the present mode of constructing burners. The nature of my invention consists in the employment, in connection with primary gas-burner for illuminating purposes, of a secondaryiburner or gas jet which is so constructed as to allow of the 'escape of an exceedingly l small quantity of gas, which is to be kept burning constantly for theppurpose of aifording a iiame for igniting the gas when it is allowed to escape from the primary burner, and which is so arranged as to be supplied with gasrin suitable quantities at all times, whether the supplyis cut ed' from the primary burneroradmitted thereto, as will be hereinafter described. It also consists inthe employment, in conjunctionwith a primary gas-burner and self-lighting gas jet, of a cock which isso constructed that the gas can be shut off from or admitted to the primary burner, or burner proper, without shutting off the gas from the secondary burner, as will be hereinafter described. It also'consists in providing for the protection of the small iiame, which is usedfor lighting the main burner, from strong currents of air,'so that it shall not be liable to become extinguished and at the same timey to adapt such protector to serve the purpose Of supplying heated air and oxygen to the iiame of the main burner for facilitating combustion, as will bc hereinafter described.

To enable others skilled in the art to understand my invention, we will describeits construction and operation.

In the accompanying drawings, figs. 1 and 2, we haverepresentsd our invention applied to the well-known form of gas-burner, which we shall term the primary burner, consisting of two burners Or tubes, A A, inclined toward each other and screwed into curved branches, VB B, so that the two iets of gas issuing from the oriices of the tubes will impinge upon each other and present a broad, beautiful iame. These branches B B terminate at their lower ends in a central tube, B', whichA is screwed on the end of the gas pipe C, as shown in gs. 2 and 3. At a short distance below the primary hurner a cock, D, is applied to the pipe C and tted gas-tight so as toallow of the gas being shut off from this burner or turned on at pleasure. This cock D is constructed with an oriiice, a, through it, through which the gas is allowed to escape freely to the primary burner, when this cock is turned, as shown in rfig.4 3. When the cock is turned with its orifice a at right angles to ,the-pipe C, as in g. 2, the gas will be cut off from the burners A A but will be allowed to flow in small quantities through the fine annular grooves b, which are made in the circumference of the cock in a plane intersecting the axis of the orifice a, as shown in figs. 2 and 3, from which grooves the gas is conducted through a small pipe, c, to the secondary burner g, as will be presently described. A division piece, cZ, is secured `in the centre of the orifice a so as to leave narrow spaces, e e, at its extremities for the purpose Of allowing gas to rush suddenly through the small pipe c to the secondary burner g, just before the full iiow or head of gas is turned on to the primary burner. Those ends of the divisional piece d which are between the spaces e e are designed to serve as valves for closing the lower end of the small pipe c, when the orifice-ct is in line with thc'bore of'tlie pipe C and the fulll iow of gas is admitted to the primary burner. When said pipe c is closed the small blue flame of the Secondary burner will be extinguished. The upper end of the taper or burner g is passed gas-tight through a hole which is drilled through the crotch of the branch pipes B B, so that the fine orifice of this burner will be `just as well.

in a vertical p-l'anelbeneath the converging ends ofthe primary burner, and sufficiently n'earthese ends to' alloW of the communication of flume to the gas issuing therefrom by the tlame of the primary burner. The small pipe c is secured in the centre ot' the larger gas pipe C in such manner that the gas rising through the orilioe oth cock D will not be materially obstructed in its passage to the primary burner. The pipe C may be a short section of pipe of sufficient length to receive the cock D and internal gas tube c, and having a female screwthread or coupling formed in its lower end, so that it can be screwed on a gas pipe in place oi' any of the old forms of burners. At the base of the curved branches B B a male-screw thread is formed on the central tube Bupon which is screwed a hollow globe, G, which encloses the burner tubes A A below their upper ends and forms an air-supply chamber for inducing currents of air to rise through the orilices z'at its base and impinge upon the ilame. The air whichrises into the chamber G becomes .heated and supplies more or less oxygen to the flame oi-` the primary burner while this burner is lighted, and when the gas is cut off from it the chamber lGr will supply air to the flame of the secondary burner and also protect this flame from being extinguished by strong currents of air.

The opera-tion of' our burner is very simple. The cock D being turned so as to admit gas to the primary burner, this gas is lighted and burns in the usual manner. In the act of shutting o` the gas from the primary burner by turning the cock D, and immediately before the full supply of gus is cut oil", one of the spaces e is brought beneath the orifice through tube c, which instantly causes the gas to jet from the secondary burner and take {ire from the nearly extinguished flame ofthe primary burner. Thus the secondary burner will be lighted in the act of'cutting off the gas from and extinguishing the primary burner. When the space c passes the orifice of tube c the gas will be conducted to this tube through the fine groeven in the cock-plug, as before described, and burned with a small blue flame. In the act of turning on the gas to obtain light one or the other of the spaces e at the ends of the division d and orice a of the cock-plug will be again brought opposite the lower end of the small pipe c leading to the lighted burner, thus allowing a full pressure of gas to this burner which will ca-use its flame tojet upward a suilicient length to ignite the gas issuing slowly from the orifices of the two burner tubes A A. When the cock D is turned fully the divisional piece d will cut off the escape ofv gas through the tube cand extinguish the taper or secondary burner. Thus the secondary burner will be extinguished in the act of admitting gas to and lighting the primary burner. It will thus be seen that the small taper is provided for the purpose of lighting the primary burner and not for giving light when the flame from this latter burner is extinguished. It is designed to make this taper so that it shall consume but a trilling amount of gas when inuse andnone at all when the primary burner is lighted.

We have described our invention applied to converging burner tubes as one practical mode of carrying it into effect, but we do not confine ourselves to this particular kind of gas burner, as we contemplate its application to other forms ofburners by making slight changes in the construction ofthe parts herein shown without, however, changing the principle of the invention as herein set forth. It isobvious that the fine groove b, which we have described as being made in thecock-plug D, may be made in the pipe C and answer the purpose designed Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. AProviding a gas-burner with a small secondary gas-taper or burner which is so arranged as to serve as a means for lighting the gas when admitted to the principal burner, substantially as described.

2. In combination with a gas-burner which is provided witha smaller gas-burner or taper for lighting it, .We claim acock, D, which is constructed so that it shall cut oif the gas from the smaller burner when gas is admitted to the main burner, substantially as described.

3. The divisional piece d, or its equivalent, applied to the orifice a of the grooved cock D, and constructed with gas-escapes c e, in combination with a self-lighting burner, substantially as described.

4. The hood or shell G, in' combination with a self-lighting gas-burner, which is constructed substantially as described.
